One of the things sleep loss increases is the risk of obesity through a combination of effects on energy metabolism. Research presented recently at the European Congress of Endocrinology highlights how disrupted sleep patterns - a common feature of modern living - can predispose to weight gain by affecting your appetite and responses to food and exercise. While several studies have correlated sleep deprivation with weight gain, the underlying cause of increased obesity risk from sleep disruption is unclear, but may relate to changes in appetite, metabolism, motivation, physical activity or a combination of factors. Dr. Christian Benedict from Uppsala University, Sweden and his group have conducted a number of human studies to investigate how sleep loss may affect energy metabolism.
